Setting up KDE Neon

Setting up KDE Neon


Over the years I tried Gnome, KDE, XFCE, and Unity for the graphical user interface. In the end, KDE won this intense battle for me. And now I am trying to have only Qt-based software for everyday use cases. And here comes KDE Neon, a Linux distribution from KDE developers with the LTS version of Ubuntu as a base and the latest KDE builds as updates.

Here are steps on how I usually configure freshly installed Neon. These are just notes for the future. Maybe someone will find it helpful.

Website of KDE Neon:

It would be best if you had a 4 GB or more flash drive and image writer software. Use the one you are comfortable with. Installation is straightforward if you have installed any Linux distribution before.


Open Konsole and run:

sudo apt install kontact
sudo apt install keepassx
sudo apt install kmymoney
sudo apt install gimp
sudo apt install libreoffice
sudo apt install elisa
sudo apt install nmap
sudo apt install traceroute


I use a stable version of Syncthing. To install it run the following commands:

curl -s | sudo apt-key add -
echo "deb syncthing stable" | sudo tee /etc/apt/sources.list.d/syncthing.list

sudo apt-get update 
sudo apt install syncthing

echo "fs.inotify.max_user_watches=204800" | sudo tee -a /etc/sysctl.conf

Open search, type Autostart, and then add Start Syncthing application to run Syncthing on user login.
